Understanding The Different Types Of Commercial Water Purification

Whether you’re using the water supply from a city, a well or another source, the quality of your drinking water depends on how it is treated. Filters, softeners, and purifiers help remove contaminants that can cause health problems or affect industrial processes. 

Reverse Osmosis 

Reverse osmosis is one of the most effective filtration methods. It removes dissolved contaminants like fluoride, chlorine, and heavy metals from tap water. However, it is not ideal for drinking or cooking as it also removes beneficial minerals such as calcium and magnesium. 

For this reason, a reverse osmosis system should be combined with carbon and sediment pre-filters to reduce membrane fouling by chlorine, iron, manganese, hydrogen sulfide and bacterial growth. The semi-permeable membranes in reverse osmosis systems are made from either cellulose triacetate (CTA) or thin film composite (TFC). TFC membranes are less prone to rotting, but they are still susceptible to chlorine damage. RO systems also require periodic maintenance to keep them in peak performance. Membranes should be replaced every 2-3 years, and carbon and sediment pre-filters should be changed at least twice a year to reduce membrane fouling. 

Water Softener 

Untreated water can leave unsightly stains on fixtures and appliances, and it can also cause buildup of scale that reduces the effectiveness of these items. In addition, hard water can clog pipes and damage equipment. To prevent these issues, many commercial facilities use water softener systems. These systems remove the calcium and magnesium that make water hard, turning it into soft water. 

The most common type of water softener is an ion exchange device. This process swaps the calcium and magnesium in hard water with sodium ions, which have no harmful effects. This style is available in both single-tank and dual-tank systems. Both types work by passing incoming hard water through ion exchange resin tanks filled with beads that swap the calcium and magnesium ions in the water for sodium or potassium ions. In addition to this style of system, some water softeners have a brine tank that must be filled with salt six to eight times a year. Adding too much salt can cause the unit to malfunction, so keep track of how much salt you have in your system and refill it when necessary. 


There are a number of different types of commercial water purification systems available. One type is deionization, which is a process that removes dissolved salts from water. In this process, a bed of resin beads exchanges hydrogen ions for cations and hydroxide ions for anions. The resulting water, which is known as deionized or demineralized, contains virtually no minerals. 

Deionized water is typically used for a wide range of applications in industries such as manufacturing, pharmaceuticals, and lab testing. It can also be used as a cleaning agent or an ingredient in food and beverage production. For example, deionized water is used to cool and lubricate industrial machines without creating mineral buildups in them. This allows for improved energy efficiency and increases productivity in manufacturing facilities.
